CORD-HOLDER FOR GRAIN-BINDERS.

SPECIFICATION forming part of Letters Patent No. 440,510, dated November11, 1890.

Application filed September 28, 1889. Serial No. 325,366. (No model.)

To a whom it may concern:

Be it known that I, JOHN F. SEIBERLING, a citizen of the United States,and a resident of Akron, county of Summit, and State of Ohio, haveinvented a new and useful Improvement in Cord-Holders for Grain-Binders,of which the following is a full, clear, and exact description,reference being had to the accompan ying drawings, making part of thisspecification.

My invention relates to the construction of the cord-holder clamp orshoe and the arrangement of the same relative to the notched cord-holderdisk or wheel whereby it is made to release the end of the cord orbandpassing around the bundle in advance of the action of the knife upon thecord, so that the cord ends, instead of being left in the cord-holder toaccumulate and clog its action, are drawn out by and discharged with thebundles. It further relates to certain details of construction andarrangement of parts hereinafter fully described and claimed.

In the accompanying drawings, Figure 1 represents in front elevation asmuch of the binder mechanism as is necessary to show my improvement,with the parts in the position they occupy after the cord has been laidby the needle and before movement of the cordholder disk. Fig. 2 is asimilar view to Fig. 1, but with the cord-holder-disk moved to grasp thecord from the needle and to release the end previously held, theknottenjaws be ing shown in section in both figures. Fig. 3 is a sideelevation of the cord-holder looking from the stubble side, the needleand a per tion of the knotter-actuating cam-wheel be ing shown insection. Figs. 4; and 5 represent, respectively, grain side and rearelevations of my improved cord-holder, showing a modification in theform thereof. Figs. 6 and 7 are also side and rear elevations similar toFigs. 4; and 5. Fig. 8 represents a horizontal section through thecord-holder disk and shoe, showing a shoe having a singleclamping-surface and the flange or lip and groove for preventing lateraldisplacement thereof; and Figs. 9, 10, and 12 show, respectively, astubble side, a grain side, and a rear elevation, and Fig. 11 a verticalsection through a crown-disk cord holder and its shoe,

showing the retaining lip or flange and groove applied thereto forholding the shoe in place.

The construction shown in the drawings,in its general arrangement ofparts of the binder mechanism, is of the Well-known Appleby type, andneed not therefore be described in detail further than is necessary toan understanding of my improvement.

Referring to the drawings, A, Fig. 3, indicates the knotter-actuat-ingcam-wheel, (in part,) B a portion of the knotter-stand or frame, whichin practice is suspended from the knotter-actuating shaf tin any usualmanner. The lower end of a pendent arm B of this stand is provided witha short stud-shaft b, on which is mounted a notched cord-holder disk 0,provided on its inner face, adjacent to the 'arm B, with a ratchet-diskC", with which a pawl d, pivoted in the lower end of an angular arm orlever l), engages for imparting an intermitting rotary movement to thecord-disk. The arm D is shown pivoted at d to a lug on the stand 13, andis provided on its horizontal forwardly-projecting arm with a roller (1which enters acam-groove at ain the cam-wheel A and imparts a vibra torymovement to the lever D in each revolution of the cam-wheel foractuating the cordholder disk. A spring (Z connects the pawl (Z with thelever D and allows it to yield to pass back over the teeth of theratchet-wheel.

While the construction shown and de scribed illustrates a simple andeffective method of actuating the corddisk and one that will be readilyunderstood, other suitable means may be employed for the purpose.

E indicates the cord clamp or shoe, formed upon or rigidly secured to anarm E, pendent from and pivoted at its upper end to the standard 13. InFigs. 1, 2, and 3 this shoe is shown doubly flanged or grooved to stridethe periphery of the disk 0, and these flanges, between which the outeredge of the cord-disk 0 moves, and which constitute the cord-clampingportion, extend only between two adjacent notches, as c and c of saiddisk in such manner that the cord received and carried by the disk intothe shoe at one end will be released and allowed to escape at the otherend of the shoe. A spring f, secured at its upper end to the standard B,at its lower end bears against the shoe E to hold it pressed firmlyagainst the edge of the disk. The pressure of this spring may beregulated by the adjustment of a bolt or set-screw f, which secures thespring to its support. G indicates the needle.

In Figs. 4 and 5 the notched cord-holder disk is shown made double andthe shoe single and pressing between the two parts of the isk.

In Figs. 6, 7, and 8 a single notched disk is employed of slightlygreater thickness than the disks of Fig. 4, and it has an annular groovegformed in one side inside of the cordnotches, and with which a lip e onthe adjacent side of the shoe engages for preventing radial displacementof the shoe. A similar lip e on the outer edge of the shoe may beprovided to overhang the periphery of the disk and prevent accidentalwithdrawal of the cord at points intermediate the ends of the shoe. Inthis construction the shoe has only one clampmg-face-via, that pressingagainst the side of the disk adjacent to its periphery.

I11 Figs. 9 to 12, inclusive, a crown-disk form of cord-holder wheel isshown rigidly secured to its actuating-wheel and provided withcordnotches at its open annular end. The shoe E is pressed by the springagainst the outer face of the rim or crown wheel, and a groove g, formedin one in connection with a rib c on the other entering said groove atthe inner end of the wheel, prevents lateral displacement of the shoeand is out of the way of the cord, which is carried into the shoeoutside or in rear of the rib by the notches in the outer edge of thedisk or rim, and the cord is consequently not liable to be caught by therib and wrapped around the wheel. The shoe is provided on its inner endadjacent to the knotter with a guard 6 which prevents the cord from theneedle from being carried into the notch in the wheel nearest to theknotter and is removed from the periphery of the rim 0 far enough toprevent any liability of the end of the cord being caught or heldclamped to the disk thereby, the latter construction being indicated bythe dotted line at a Fig. 12. An outwardly-inclined finger e on the same(inner) end of the shoe serves to draw the cord from the needle towardthe notched edge of the wheel, and fingers at the outer end of the shoeserve, one e inclined on its upper face, to deflect the cord and carryit into the not-chin the wheel at that point, and the other 6 extendingaround inside of and over said notch, serves to throw the cord from theneedle off the end of the wheel and prevent it from being wrappedthereon.

In all the several constructions shown the receiving end of the shoe orof the flange thereof is beveled orinclined inward to cause the cordwhen acted upon by the notch in the disk to pass under the shoe orflange, and the clamping-surface of the shoe extends only between two ofthe notches of the cord disk indicated at h, after having been carriedaround a previous bundle and receivedinto the cord-holder and with theparts in position to again take the cord from the needle. In Fig. 2 theoord-holder disk has received its rotary movement and has carried thecord from the needle down into the clamp or shoe, while the end lefttherein in the previous movement of the parts is carried through theclamp and released at the end thereof, the notch carrying said endpassing beyond the clampingsurface of the shoe in such movement of thedisk. Just at this moment the knife is operated in any usual orwell-known manner to cut the portion of the cord coming from the bundleand extending up through the holder to the needle, thereby leaving thenew end in the holder, while theformer end freed from the holder, asdescribed, is drawn out by the bundle as the latter is discharged,instead of being held by, and therefore cut off and left in the holderto clog it, as in the former constructions. In this movement of thecorddisk the two strands are moved from the inclined position relativeto the knotter (indicated at is) into about the same horizontal planetherewith,thereby to that extent yielding cord to the knotter.

In Figs. 1, 2, and 3 the cord-wheel is shown arranged to move in a planesubstantially at right angles to the path of the needle, which is shownpassing between the arm which supports said wheel and that whichsupports the shoe; but it may be arranged to move in a plane oblique tothe plane of the needle, or in case the crown-wheel is employed it maybe arranged to move in a plane substantially parallel therewith; but inall cases it is preferred to so arrange it as that the feed or directionof movement of the cord through the clamp will serve to yield cord tothe knotter, and to that extent facilitate the formation of the knot.

Having now described my invention, I would state that I am aware that itis not new to shorten or cut away one flange or rib of a double-flangedshoe to facilitate the discharge of the short out ends of the cord afterthe same have been cutoff to free the bundle and left in thecord-holder; but in such construction one flange has always been leftsufficiently extended to hold the cord until after it was out, and thecut end was thus left in the holder.

I am aware that the clamping-surface of the shoe has been made less inlength than the distance between adjacent notches in the cordholderdiskoperating in connection therewith;

but in all such constructions the movement of the disk relative to theshoe has been such as to leave the end of the cord hold fast in the shoewhen the knife acted to sever the cord, and the short cut end of thecord was thus left in the holder, whereas in my construction the end ofthe cord is carried through the shoe and released in advance of theaction of the knife on the other strand of the cord, (that coming fromthe needle through the holder,) so that only the latter is cut, and theend of the cord is thus drawn out and discharged with the bundle,instead of being left in the holder to clog it.

WVhat I claim as new is- 1. The combination, in a grain-binder, of aknotter, a rotary cord-holder wheel or disk having a series ofcord-notches and provided with means to impart an intermittent movementthereto during each revolution of the knotter, a knife between theknotter and disk to cutthe cord, and a clamp or shoe to hold the cord onsaid disk, theireceiving end of the flange of said shoe being inclinedto permit the notch in the wheel to carry the cord under the flangetoward the terminal end of cord-holder wheel, a double-flanged clamp orshoe arranged to straddle the periphery of said cord-holder wheel, theflange of said shoe farthest away from the knotter arranged to clamp thecord running from the needle and the receiving end of the flange nearestthe knotter inclined to guide the cord running to the knotter under saidflange, and a spring to hold said shoe on the cord-holder wheel, saidclamp or shoe being arranged in respect to the intermittent movement ofthe notch carrying the cord, substantially as described, so that the endof the cord will be carried by the notch past the clamping-surface ofthe shoe, for the purpose specified.

3. The combination, in a grain-binding knotter, of a rotary cord-holderdisk or wheel having a series of notches to receive the cord and a clampor shoe to hold the cord thereon, said wheel and clamp being providedone with a groove and the other with a retaining lip or flange engagingsaid groove, said flange and groove being located below the bottoms ofthe cord-notches and extending in the direction of the travel of thewheel, and said clamp or shoe having a clamping-surface extendingbetween two of said notches only, substantially as described.

In testimony whereof I have hereunto set my hand this 26th day ofSeptember, A. D. 1889.
